Water Pumps and Accessories

Speedway Motors keeps you cool with racing radiators and performance cooling system components. With many sizes and styles of aluminum radiators available, you can ensure a good fit no matter what type of car you race. Speedway also has the racing fans, water pumps, pulleys, hoses and thermostats you need to get the most out of your race car's cooling system. Trust Speedway to keep your race car cool!

Original Flathead water pumps have always suffered from unreliable bronze bushings and carbon seals. They almost always leaked and even Ford manuals warned mechanics not to tighten fan belts too tight. The excess slack allowed belts to slip and lose contact with the generator and water pump pulleys, causing more cooling and power problems.

Speedway's completely new water pumps feature severe-duty roller and ball bearings, close tolerances and modular impellers to provide maximum flow and reduce cavitation. They also have modern ceramic seals on a heavy duty 5/8" shaft, making the assembly exceptionally strong and more efficient. All mounting areas are spot faced for improved fit and sealing.

All-new high-nickel iron castings

Severe-duty roller and ball bearings

Ceramic seals on sturdy 3/4" shaft

High-flow modular impeller reduces cavitation

Gaskets included

For systems with 5/8" drive belts

Factory replacement for 1937-1948 Ford and Mercury cars and trucks. Includes gaskets.

Our newest high volume electric water pump has been machined from billet aluminum and the fit & finish is excellent. This pump is durable and light weight, but is still able to cycle up to 35 gallons of coolant per minute! Electric water pumps reduce impeller drag experienced with mechanical water pumps at high rpms and are recommended for high performance racing applications.

Includes all required seals, fittings and hardware (when adapters and pump are combined)

Precision machined billet aluminum housing

Light weight

35 gpm rating

Eliminates impeller drag found in mechanical water pumps

Black anodized finish on motor, all other parts polished

Note: For complete assembly, simply select the Small Block Chevy adapters(911885) or the Big Block Chevy, Small Block Ford or the Big Block Ford adapters listed below that your application requires and the pump body.

These racing combo power steering pump mounts are ultra-lite and slotted to be used with standard and raised cam engines. These mounts eliminate the need for different mounts when you have different block designs. The back of this mount is closed off to only allow a cam spud through. No more dirt getting in to wreck the pump bearing!

Speedway Cast Aluminum double groove pulleys for Small Block Chevy feature a 20% reduction. Reduction pulleys have a smaller diameter which slows the speed of your fan, water pump, and alternator to reduce drag for more top-end horsepower. Plus, high RPM water pump operation is improved due to reduced fluid cavitation.

Speedway's adjustable water pump is tried, tested and true. It has great flow, superior quality and standard features that are typically only available on water pumps costing twice as much. State-of-the-art aluminum casting and a precision impeller provide equal flow to both cylinder banks. If you're using a cog belt on your race car, this is the pump you want since it's adjustable. The 1/2" mount holes in this pump are larger than normal, allowing it to be moved up or down slightly to help with belt tension.

Adjustable mounting holes

High flow and pressure rates

Adjustable cam stop

Extra-thick fan hub

3/4" inch heavy duty bearing

Pressed-fit and set-screw-retained fan hub

Large-diameter shaft and reinforced housing make it ideal for oval-track applications

Note: This kit will work with most "short" water pumps, but hub heights do vary slightly depending on manufacturer. Some modification of the mounting holes may be required. This kit WILL NOT work with "long" water pumps as the crankshaft to hub center height is 5/16" greater than that of a "short" pump.

Moroso first pioneered the aluminum water pump for racing over 15 years ago. Over the years, continual improvements have resulted in providing the best cooling system components available for competition use.

Computer designed housing cast from 356-T6 aluminum

Lightweight impeller maintains consistent coolant temp throughout the water jacket

Uses new, OEM cast iron castings precision machined and assembled by Stewart Components to their exacting standards. They feature higher flow and pressure for better cooling. They have a 3/4" bearing and 5/8" shaft.

Castings are internally modified for performance and reliability

Compatible with stock lines and brackets

Precision ground hub for perfect pully alignment

Equal flow to left and right cylinder heads

Recommended for stock, OEM, or mild performance applications

One year warranty

Note: If using a mechanical fan, we suggest using a 3/4" shaft water pump.

Each aluminum pump is manufactured from T6 aluminum and features a revised impeller entry with curved vanes for maximum flow, pressure and equal distribution to both sides of the block. It also features a unique seal assembly for leak proof operation.

Fan hub has a 1-3/4" bolt pattern

The lower hose comes out on the driver's side and uses a 1-3/4" lower hose

Includes a heavy duty bearing and 3/4" shaft and pulley snout; and 1/2" NPT hole on the passenger side (for heater hose) and on the top (for by-pass hose). Thicker (0.100") stamped steel rear plate. Weighs 6 lbs.
